facebook has it's uses for promotion. But there are some things many
people overlook in the terms of service that you should be aware of.
This came up in a FB jewelry/metalsmith/lapidary group I'm in. A lot
of people, well, most, never read the Terms of Service of anything,
let alone setting up a business FB page. There are certain things
which, if FB choses, they can use as grounds for booting your page
from their site, including having your contact details/website URL
etc embedded in your cover photo. Read more about it all here:
While most people do many of these things and never have an issue,
if FB wants to shut down your page or gets complaints, you could
loose your page, all it's likes and subscribers without any recourse
other than to start over.
